Filed: 1936-06-18
Abstract: 480,349. Coating metals with metals ; fluxes. BROWNBACK, H. L. June 18, 1936, No. 17027. Convention date, July 5, 1935. [Class 82 (ii)] [Also in Group XXII] Casting composite articles.-A ferrous bearing shell 1 or other backing is lined with leadbronze, copper-lead, brass, or other cuprous bearing alloy by welding or otherwise securing it to a crucible 6 containing the bearing metal 9, heating to melt this out of contact with the backing, as shown, and keep it molten while brought into contact with the shell, by inversion or rotation about the axis of the shell in a horizontal position, and so kept for 2 to 6 min. to allow the copper to penetrate. The bearing is then rapidly cooled while in lining position. If the alloy contains much lead it should be shaken before and after the soaking step. If the shell is rotated this may be slow for the soaking step but must be rapid just before cooling. If the furnace has an oxidizing atmosphere, salicylic acid or other volatile flux may be introduced into the crucible. The shell is preferably first pickled, and coated internally with copper and externally with a hardening compound 1.0. When the shell is precoated with copper the soaking step may be omitted. If the casting is done by inversion a core 3, having a closed end 4 with a vent 5 is preferably welded to the annulus 2. In modified arrangements the shell is coated both inside and out when inverted by the same or different alloys, this arrangement with two crucibles 6a, 6b being shown in Fig. 4. The Specification as open to inspection under Sect. 91 comprises also a modification in which a steel strip is cleaned, passed through. a copper-coating bath, and fed to a furnace while a measured amount of bearing alloy, in the form of powder, strip, or wire, and, if desired, a volatile flux, is placed thereon. The coated strip is cooled by a jet of fluid. This subject-matter does not appear in the Specification as accepted.

Abstract: 838,038. Jet propulsion nozzles. BOEING AIRPLANE CO. May 29, 1958 [Aug. 20, 1957], No. 17197/58. Class 110 (3). [Also in Group XXXIII] The duct leading to the nozzle of a jet propulsion engine and the nozzle itself are formed by the interior wall of a housing 9, Fig. 2 (part radial section) which, going downstream, first diverges and then converges, and by a bulbous plug 1 axially slidable on a central tube 91 by an actuator 10. Normally, the plug is located so that its greatest diameter is in the region of the greatest diameter of the wall, to form a throat in the duct. The plug then covers a set of vanes 2 housed in recesses 97. The plug can be moved axially to vary the area of the throat and nozzle, and in the position shown exposes the vanes 2 which may be swung radially as shown by an acutator 21 to split up the jet stream for noise suppression. The vanes are channel-shaped, open downstream, so that ambient air can flow radially inwards along the channels and mix with the jet. The decrease in nozzle area caused by extending the vanes is compensated for by axial movement of plug 1.

Title: Improvements in or relating to telegraphic receivers and retransmitters
IPC: H04L25/20
Filed: 1930-06-04
Abstract: 356,208. Telegraphy. CREED & CO., Ltd. and CREED, F. G., Telegraph Works, Croydon. June 4, 1930, No. 17223. [Class 40 (iii).] In a start-stop receiver or retransmitter, means are provided for preventing the registration of a false signal when the start-stop shaft is wrongly relased in consequence of signal-distortion. The invention is described as applied to the stripperforating cable-code receiver described in Specitication 204,398, [Class 40 (iii), Telegraphs, Electric], in which a selector bar r is positioned for a dot or a dash by a polarized relay which actuates it through the rod t, either the dot punch g or dash punch h being driven to the right by the selector projection r<3> when the link n is actuated by the cam w. The cam shaft 2 is released by the pawl 6, carried by the release rod 11, on the receipt of each dot or dash signal, and should then perform one revolution only ; but if the signal be prolonged by distortion a further revolution may be initiated without the occurrence of a fresh signal. In order to prevent the registration of a false additional signal in this event, a member K, interposable between the punch-actuating parts n and r, is positioned by the release rod 11 which is controlled by a non-polarized relay to which the signals are applied. Thus a signal is not registered unless the incoming signal persists long enough to interpose the member K at the moment when the cam w actuates the rod n. In order that the punches may not be damaged if a distorted signal tends to move the selector r during a punching operation, the rod t is resiliently connected to the selector r, Fig. 5 (not shown). The subject-matter claimed in Specification 341,084 is disclaimed.

Title: Improvements in or relating to pay television distribution systems
Inventor: PARTINGTON GEORGE EARNSHAW
IPC: H04N7/173
Filed: 1962-05-09
Abstract: 992,725. Electric selective signalling. PAYVISION Ltd. June 21, 1962 [May 9, 1962], No. 17835/62. Heading G4H. The invention provides a pay television system wherein the subscriber can select one of a number of pay programmes and be charged the appropriate sum for it later. He may leave the programme temporarily without being charged again when he returns to it, and he can use his receiver to receive free programmes. A key is provided to guard against unauthorized use of the receiver. The several programmes available are transmitted from a central station Tu. Fig. 1, to billing centres BL, whence they are distributed over lines L to each of which is connected a large number of receivers. Each subscriber has a switch S by which he can select any one of several channels. With key K1 in the position shown switch S selects a free programme. However, when switch S is turned to select a surplus channel, channel X, details of the charges for the pay programmes are given. If now one of the switches A, B, or C is actuated and switch K moved to its second position one of the three pay programmes appears on the receiver screen, the incoming pay programme signals being altered to the frequency of channel X by unit FC. Movement of key K to its second position locks up relay R. Contact K2 automatically opens when the key is released but the pay programme selected is maintained due to relay R self-holding. If K1 is now moved to the position shown, switch S can select a free programme, and subsequently the subscriber can return to the selected pay programme without being charged a second time for that programme. When a pay programme has been selected a carrier, which is characteristic of the receiver, is modulated by one of three frequencies indicative of the pay programmes, and the modulated carrier signal is transmitted to the billing centre BL. At the end of a pay programme the vision and sound carriers are switched off for a time sufficiently long a relay to break the self-holding circuit of relay R and hence the receiver stops sending a singal to the billing centre. At the billing centre, Fig. 2, switch RS connects in circuit each of the lines L in turn. While the switch arm rests on any one contact, an oscillator VL0 scans over a frequency range which includes all the carrier frequencies of the receiver return signals. The signals are demodulated and filtered to provide, at any instant, one signal on one of three channels which is fed to a computing and recording unit RD which records which subscriber has selected which pay programme. Counters indicate the number of subscribers using each particular programme.
